Title: An improved automatic film winder for film cameras
IPC: G03B17/42
Filed: 1921-08-08
Abstract: 187,067. Griffiths, C. E. Aug. 8, 1921. Magazine hand cameras with connected action between shutter and changing-mechanism.-Relates to mechanism actuated from the shutteroperating device of a roll-film camera whereby, after each exposure, clockwork-driven means con. trolled by perforations in the film is caused to wind the exposed portion on the spool. The film is adapted to be wound on a spool 8, Fig. 2, actuated through toothed wheel gearing by a clock-spring in a drum 18 fitted with a winding handle 24 and ratchet retaining-gear, the whole being mounted on the side of the camera body within a casing 84. The releasing-gear is actuated from a spring-controlled push-pin 32, Fig. 3, connected to the shutter release cord. When this pin is pressed a pin 40 moving therewith rocks on its pivot 42 a lever 41, causing the nose 45 of a spring-controlled detent 43 pivoted on the lever to drop in front of a stud 54 on a spring- controlled slide 51 carrying a stud 56 engaging a slot in a lever 58 turning on a pin 59 in the casing, the pin carrying a stop 60, Fig. 8, engaging a fly 61 on a spindle 62 geared through wheels 63, 64 to a wheel 21 in the clockwork train. On the release of the pin 32 after the exposure, the pin 40 carries back the lever 41, and with it the slide 51, which through the stud 56 rotates the stop 60 out of contact with the fly 61 and releases the clockwork. Towards the end of the backward travel of the pin 32, a stud 47 on the casing rocks the detent 43, releasing the slide 51; but this is prevented from returning to its normal position by the engagement of the film with a roller 52, Fig. 2, on the rear part of the slide 51 which is bent round at right angles. When the required length of film has been wound, the roller 52 drops, through one of a series of holes 69 in the film, into a recess in a croos-bar on the casing, permitting the slide 51 to return to its normal position and, through the stop 60, to arrest the clockwork. A governor is provided to regulate the speed of the clockwork. A ratchet gear and handle 17, Fig. 2, permit the film to be wound by hand independently of the clockwork. To prevent shock on arresting the clockwork, the fly 61 is frictionally held on its spindle by a spring- pressed pin.

Title: Improvements relating to thermionic valve amplifiers
IPC: H03F3/52
Filed: 1931-07-23
Abstract: 382,307. Valve circuits for wireless reception. IGRANIC ELECTRIC CO., Ltd., 147, Queen Victoria Street, and PADDLE, L. H., 2, Burlington Gardens, Chiswick, both in London. July 23, 1931, No. 21058. [Class 40 (v).] A multivalve amplifier is characterized by the feature that the output or coupling impedance is located between the cathode and the negative pole of the H.T. supply, and by the feature that the H.T. supply is common to both valves. In Fig. 1 the primary winding 4a of the intervalve coupling is on the cathode side of the H.T. source 3, but is not in the input circuit of the valve 1a. Resistances 6a, 6b provide grid-bias for the two valves 1a, 1b. The filaments are energized by separate windings on the supply transformer 10. In Fig. 3 the valves 1a, 1b are anode-coupled in the ordinary way, whilst the output valve 1c is cathodecoupled to the loud-speaker through a coil 4c. In Fig. 4 the valves la, 1b are cathode-coupled, and by adjusting the value of the coupling- impedance 4a, 16, grid current flowing in the valve 1b can be counterbalanced by the anode current from the valve 1a, so that the valve will amplify over a positive grid-voltage swing without distortion. Fig. 7 shows a push-pull arrangement in which the output from the two valves 1a is cathode-coupled to the valves 1b, and grid current is again neutralized. The Provisional Specification also describes a singlevalve amplifier with a cathode-coupled output.

Title: Improvements in high speed jack
IPC: B66F3/14
Filed: 1919-08-29
Abstract: 153,988. Percival, S., (Duff Manufacturing Co.). Aug. 29, 1919. Jacks.-Relates to a rapid-action screw-jack. The ram 30, Fig. 3, is slidably but non-rotatably mounted in the standard 3 and is formed with a shoulder which rests on a nut 40. A quick-threaded screw 20 engages the nut 40 and is supported by a broad end-thrust ball-bearing 21. The screw 20 is connected by gears 26, 49 to a vertical shaft 46 which is connected by bevel-gears to an horizontal shaft 52 turned through ratchet mechanism 53, 54, Fig. 2, by raising and depressing the handle 57. A ratchet-wheel 58 secured to the shaft 46 is engaged successively by a series of pawls 64 mounted in a member 60 free on the shaft which is formed with a worm-wheel 69 on its upper part. A worm 70 formed on a shaft 71 engages the worm-wheel and prevents the lowering of the ram when supporting a load unless the shaft 71 is turned by the handle 77. When the shaft is turned in the opposite direction, the ram is raised rapidly. When the jack is not loaded, the ram is lowered by coupling the member 60 and shaft 46 by a clutch collar 84 and then actuating the handle 77. The collar and member 60 are normally separated by a spring and are engaged by depressing the button 95. The jack is mounted on wheels 7 and can be wheeled about by disengaging the handle 57 from the ratchet mechanism and engaging it with sockets 102, 103, Fig. 1. Carrying- handles 105 are also provided. When the ram has been raised to the limit of safety, it is engaged by the nose of a dog 107 pivoted on the casing. Further movement of the ram breaks the connexion between the dog and the casing, and the fall of the dog warns the operator. The casing is closed so that the whole of the mechanism may work in a mass of grease.

Title: Improvements relating to the generation of electrical pulses
IPC: H01H50/72
Filed: 1943-12-21
Abstract: 571,963. Electromagnetic interrupters. SIEMENS & GENERAL ELECTRIC RAILWAY SIGNAL CO., Ltd., and RIDDLE, H. J. Dec. 21, 1943, No. 21406. [Class 38 (v)] Electric pulses are generated by a vibrating- column mercury switch 1 having magnetic armatures 5 floating on the mercury in the outer limbs, which armatures are attracted by pole pieces 3 of an electromagnet having windings 2 in the circuit of which is a switch 71 actuated by relay 7, On attraction of the armatures, mercury rises in the middle limb making the circuit of relay 7 through the mercury and contacts 11, 12, thus opening switch 71 and de-energizing windings 2. The mercury in the centre limb recedes until the relay circuit is broken, thus causing renewed energisation of the electromagnet. Oscillation of the mercury thus takes place and relay 7 operates contacts 72 giving pulse outputs. Modifications are described in which normal contact with 11 is broken by upward attraction of the armatures, Fig. 2 (not shown), and in which energisation of the windings 2 is affected by removing a short-circuit from them by movement of the mercury, Fig. 3 (not shown). A number of switches of different periodicities may be adapted for selective inclusion in circuit by a manual switch, Fig. 4 (not shown), this arrangement being adapted to that shown in Figs. 6-8 of Specification 565,267. The relay 7 may be of the spring- contact type, or alternatively may comprise a mercury container in which two bodies of mercury are caused to coalesce by steel balls serving as armatures of an electromagnet and floating on the surface of the respective mercury bodies, Figs. 5-7 (not shown).

Title: Nitroarylamido-phosphoric acid esters
IPC: C08G18/77
Filed: 1959-06-24
Abstract: The invention comprises nitroarylamido phosphoric acid chlorides of the general formula <FORM:0873015/IV (b)/1> in which Ar is a phenyl radical which may be substituted by one or more chlorine atoms and/or C1-C4 alkyl radical or C1-C4 alkoxy radical, or a naphthyl radical, R is a C1-C4 alkyl radical or an aryl radical or another Ar(NO2)1-2 group and X is a further chlorine atom, a secondary or tertiary organic amino group or a C1-C4 alkoxy radical or another -N(R)-Ar(NO2)1-2 group. They may be obtained by dissolving a compound of the general formula Ar-N(R)P(O)(X)(Cl) in concentrated nitric acid at a temperature within the range of -10 DEG  to 10 DEG C. and precipitating the resulting nitro compound from the reaction mixture by the addition of ice water.  Compounds in which R is hydrogen may be obtained similarly by nitration of the corresponding nitro group-free compounds.  The products of the first given formula may be treated to reduce the nitro groups to amino groups and these amines may be converted by known methods to isocyanates and the chlorine atoms then or before such conversions may be replaced by ester or amino groups to form intermediates for polyisocyanate or polyurethane type resins.  Alternatively, the 1 or 2 free chlorine atoms present may be replaced by ester or amino groups to form compounds having pesticidal properties.
